Ok. So I've been watching SnK a lot lately and I've thought of something. So on the first episode, when the colossal titan breaks through Wall Maria(I think), you can see the titans behind the colossal titan, but if you know or remember, the titans eat titan shifters, so why don't all of the titans eat the colossal titan? This is just a theory, so if it's wrong I'm sorry or if you have the answer, would you please tell me? Have a fantastic day everyone and I completely recommend watching SnK.
